To all whom t may concern:

Be it known that I, OSCAR C. RIXsoN, a citizen of the United States, residing at New Rochelle, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Cremorne Bolts, of which the following is a full, clear, and eXact description.

`This invention relates to Cremorne bolts adapted for use with swinging closures such as easements, doors and the like.

One of the objects of the invention is to provide a Cremorne bolt which is adapted to be attached to windows or other swinging closures having the portions thereof to which the bolt is attached of relatively narrow width.

Another object of the invention is to provide a Cremorne bolt having its bolt rods and guides so constructed that the bolt rods may be highly finished without liability of the finished surface becoming scratched or otherwise marked.

A further obj ect of the invention is to provide a Cremorne bolt in which the guides which maintain the sliding bolt rods in position are entirely concealed from view and yet the bolt rods are securely held from rattling or otherwise becoming displaced.

A further object of the invention is to provide a Cremorne bolt which is interchangeable, that is, may have its handle arranged for rotation in the righthand or lefthand direction.

With these and other objects in view, which will be apparent from the detailed de- A scription hereinafter to follow, the invention consists of the constructions and combinations of parts which are set forth in the appended claims.

In the drawings:

Figure l shows a portion of thedoor or casement equipped with a Cremorne bolt constructed in accordance with the principles ofthe invention;

Fig. 2 is a plan of the bolt actuating mechamsm, the casing being partially removed to more clearly show the parts;

Fig. 3 is a central vertical section through the mechanism disclosed in Fig. 2;

Fig. t is a view similar to Fig. 2, the connecting links being shown in reverse position v a view einiiar te Fig'. 2, showing the position of the links when the bolt rods are retracted;

Fig. 7 is a view showing the guide in elevation;

Fig. 8 is a transverse section through the bolt rod and guide;

Fig. 9 is a detail showing the lstud and the end of the bolt rod;

Fig. l0 is a detail of a modied construction, in which the actuating mechanism is operable by handles upon both sides of the swinging closure.

The Cremorne bolt constituting this invention is adapted to be utilized with swinging closures, such as doors and easement windows, with which Cremorne bolts are ordinarily used, and in Fig. l asection of the easement or window is shown consisting of two sections l and 2, one section having a stile or astragal 3 forming a part of its sash 4. A portion of the window frame is shown and designated 5. The Cremorne bolt which is mounted upon the stile or astragal 3 comprises two sliding hollow bolt rods 7 and 7', which are supported alongtheir length at spaced intervals by concealed guides 9 as will be later described. The ends of the bolt rods are adapted to fit into strikes 9 inserted in the window frame and floor when the two bolt rods 7 and 7 are moved to their projected position by the actuating mechanism. The bolt rods 7 and 7 are hollow being formed from a strip of sheet metal which is bent or stamped to provide a semi-cylindrical wall with spaced bent over edges or flanges forming the bottom face thereof. This construction therefore constitutes a hollow bolt rod having a central longitudinal passageway therethrough communicating with the slot formed between the flanges forming the bottom face of the rod. This feature of the invention is of importance since by providing a hollow rod of this character the guides 9 areentirely concealed from view, as will be later described.

The inner ends 10 and l1 of the hollenr rods 7 and 7 are flattened, as is clearly shown in Fig. 9, to provide a solid portion of a double thickness of metal, the 3 iiattened portion of the rods being of slightly :greater 'width theysemicyliriclrical portions I frein sheet metal.

thereof. The two thicknesses of the fiattened: endA portions are secured together by means of a headed stud 15 which is secured to a washer 16, the two thicknesses of nietal being held between the head of the stud and the washer 16. The flattened end portions 10 and 11 are covered with a casing 17 which isistainped fromi sheet nietalso as to provide a substantial U-shaped piece having a slightly enlarged inedial portfiolr 1S. This casing is secured to the stile 3 by nieans of screws 19 which pass through suitableV holes in the casino". Two of the screws also pass through the flattened end portions which are provided with elongated slots 20 of suihcient length to permit the bolt rods 7 and 7 to* be projected and retracted by an actuatin mechanism which will now be described.

hilo` bolt' rods 7' and 7 are connectedl at their inner ends to the curved"` links 22 and 23which'lil1ks are preferably cuty or stalnped Each one ofthese links has a hole" or aperture at one end thereof into which t'heh'eadV ofthe` stud 15 nts, the link'bein'g freely removable from the stud to permit the parts to be disassembled for the purpose of: reversing the `direction of rotation of' the actuating handle as will be later' refer ed to. The innerl or adjacent ends offthe' two links and`23" are pivoted between` two d'sks 2i and 25 by nieans of pivot pins 26 which permanently secure the disks and links together.' The disks 211 and 25 are substantially circular in shape and are' provided with centrally-disposed alining square apertures or hol'es through which a spindle 27- passes,.the spindle projecting beyond the casing 17 and carrying a handle 28 which is secured tothe endI of the spindle by setscr'ew 29,` asis the usual construction. The inner end of the spindle 27 is preferably provided with an enlarged head 30 which prevents inadvertent separation of the s )indle from the disks.

Tl e links 22 and 23 are slightly curved as shown in Fig. 2 so as not' to interfere with the screws 19 which secure the casing to thestile 3 when the links are in their projected position as shown in this View. The curii'ature ofthe links also essential to prevent interference with the spindle 27 when the bolt rods are in their retracted position' as shown in Fig. 5, since it is obviens that upon rotation of the spindle in a counter#clockwisel direction, as is shown in Figs. 2 and1 5, the links and disks Will be inovedfron'i the position shown in Fig; 2 to the' position showninFig. 5 to thereby retract thebolt rods. Theends' 1`Oand 11 of .the bolt rods'wliich-,slide within the casing 17 are prevented from rattlingv therein by the enlarged end?A .portions 1B and 1st engagingthe side Waillsfof. the casing, fi's'will be clear froin'F'ggfS thebolt'rods themselves do' not therefroniby the washers 16 which therefore serve to reduce the friction and' hence the effort required to operate the bolt rods.

To hold these bolts in their shot or locked position a locking pin 31 may be utilized which. is permanently secured to the casing 17 by a flexible chain or cord This locking pin passes through an opening 33 inthe casing and through one ofthe slots 20 in a bolt rod and end engages in a recess 34 provided in the stile or astragal so that when the pin is placed in position its en gageinent with the endwall* of the slot 2O will prevent the-bolt from' being retracted.

The handle 28 shown in Figs. 1` andl flis preferably applicable foruse with easement windows which open inwardly, that is, with swinging'closures where the h'aiiidle cannot engage the other sectioir of the closure. Where, however, the easement' window opens outwardly, the handle 2Sy should be replaced by a lever handle siniilarv to the lever handle shown' in Fig. 1017 since if a handle", such as is" shown at 2S which is in a crosswise position. when thebolt rods are retracted, wereutilized with outwardly swinging closures, the endof the handle would engage the other section of the swinging closnreunless thelhandle could be spaced a sufficient* distancek therefrom which is sometimes impractical with they types of easement windowsin conunon use; W here a lever handle, such as the handle 35, is utilized, to render the construction inten changeable so that the bolt' rods may be retracted by swinging the lever handle 35 to the left or right, as may be required with dilferent` types ofswinging closures, the construction described permits the parts to be interchanged without* the use'oftloolsand in an entirely simple nianner, requiring only that the handle 27 andthe casing be reinoved and the links 22 and 23I slipped ott' the ends of the studs 15. The spindle is then driven from the plates or disks and 25. Jthe linksl andi disks reversed and the spindle again` driven into place, the casing and' handle being again assembled" as teL scribed; The parts will then be inthe posiL tion shown in Fig. fl, which' will perinit the bolt rods to be retracted when the handle is rotated in an opposite directioii to that shown'inFig 5.

Referring now to Figs. 6, 7 and'S', one forni of a guide which rnayfbev usedtohold the hollow bolt rods 7 and 7" in position upon the stileor astragal is'show'n. Each of thev guides is stamped fromv ak strip of sheet inetal to provide base pieces Ll0 and' ll1 which are adaptedl to rest against` the astragal or stile, and' an intermediate body portion l2 which` is* spaced; frorn` the' stile or astragal, asis shown in` Fig. 6.- lh'e*l guide is secured tov the stile, or astragal by screws fli4l andwt' to' prevent thebodyfportion 42 from bending it is preferably provided with integral lugs or ears 46 which are formed by cutting U-shaped slots and bending the free portions downwardly. The base pieces 40 and 4l are connected to the body portion 42 by connecting strips 43 which are of less width than the base and body portion to permit the body portion to fit inside of the hollow bolt rods 7 and 7', as is clearly shown in Fig. 8, the body portion therefore serving as a cross head to retain the bolt rod in place through its engagement with the flanges on the hollow bolt. These anges rest upon the base pieces 40 and 41 so as to space the bolt rod from the astragal and to eliminate undue friction. It is obvious that different types of guides may also be employed which have an enlarged portion or cross head corresponding to the body portion 42 to lit within the hollow bolt rods and maintain the same in position.

It is also to be noted that the guide when the Orem orne bolt is in position is concealed from view and has no portions thereof engaging the visible portions of the bolt rods which will permit the bolt rods to be given a high ornamental finish without liability of such finish becoming scratched or marred during' the operation of the rod. In this` connection it may also be stated that the casing 17 is also out of contact with the portions of the bolt rod which become visible when the bolt rods are projected so as to eliminate any danger of these portions of the bolt rods becoming unsightly by having their finish injured through sliding engagement with the walls of the casing.

The construction shown in Fig. 10 is utilized when it is desired to actuate the Creinorne bolt from both sides of a swinging closure. In this construction the spindle 27 instead of having an enlarged head 80, as in Fig. 3, is extended a suflicient distance beyond the disk 24 to permit a sleeve 48 to be slipped thereover and secured thereto. This sleeve also receives the end of a square spindle 49 which passes through the astragal or stile of the swinging closure to the opposite side thereof where it is secured to the lever handle 35 or other suitable handle, the handle bearing against an escutcheon plate 50 of the usual type. In order to convert the construction shown in Fig. 3 to the one shown in Fig. 10, it is only necessary to replace the spindle 27 by a spindle 27 which may be done without the use of tools, the Gremorne bolt described being therefore capable of universal application to all types of swinging closures with very slight changes of construction, which changes may be effected in an entirely simple manner.

One advantage of the construction which may be referred to is that it is adaptable for use with swinging closures or easement windows havingnarrow astragals or Stiles, since the enlarged portion 18 of the casing is the widest portion of the entire construction. v I claim:

l. In a bolt construction, the combination of a hollow bolt having a longitudinal slot therein and a guide comprising a plate the two opposite ends of which are depressed, the intermediate portion being connected with the depressed ends by narrow necks, said intermediate portion being located inside of the bolt, the depressed ends outside thereof and the necks traversing the slot.

2. In a Cremorne bolt construction, a pair of hollow reciprocating bolt rods each having a slot in the rear face thereof, guide plates wholly hidden behind the rods and having guiding parts projecting through the slots in the bolts, actuating mechanism for the bolts connected to the inner ends thereof, a casing surrounding the actuating mechanism and the adjoining ends of the rods, said casing having inner portions in guiding contact with the rods and other portions equal in length to the movement of the rods extending beyond the guiding portions and which cover but do not touch the rods.

It witness whereof, I subscribe my signature.
